提出了一种检测冷却水结垢性能的微电解方法，适用于判断阻垢水处理的效果。探讨了电流密度、电解时间和搅拌速度等因素对此法的影响。试验结果表明，阴极垢量与Ｌａｎｇｅｌｉｅｒ 指数线性相关；水处理效果不同时垢量差别明显。 A micro-electrolysis method for detecting the fouling performance of cooling water is proposed, which is suitable for judging the effect of anti-scaling water treatment. The effects of current density, electrolysis time and stirring speed on this method were discussed. The experimental results show that the amount of cathode scale is linearly related to the Langelier index; when the effect of water treatment is different, the amount of scale differs significantly.
